But that is the point of the ending, even Yoohan is dissatisfied with his own revenge. The good thing is that he realizes that his life has meaning and he wants to live, even after the death of his family, he wouldn't have gained anything from the revenge anyway -> so I guess the viewers should accept that as well.
Anyway his OG plan was was to seduce Executive Director Yoon and make Myeongshin lose the role of The Memory.. so he actually succeeded his plan.
And there was one point in the story where Yoohan was seen in his flat with his stuff, and he barely had anything, he is not even wearing different clothes lol so I guess Jay only helped him haha
The end is so touching, my only complaint is myeongshins karma didn't feel all that satisfying to me. But omg.. yoon put that message for yoohan!! He wants to be the reason he livesss I'm crying
But why did he have to throw out his stuff that's so extra
